  • Patent number: 8206456
    Abstract: The present application describes an implant system useable for positioning an implant device such as a device useful for restricting passage of ingested food into the stomach. In one embodiment, the disclosed system includes a plurality of anchors that may be coupled to tissue within the stomach, or to a tissue tunnel formed by plicating stomach wall tissue. The anchor includes a loop. During use, the implant device is inserted through the loop and expanded such that it retains its position within the loop until removed. Instruments for implanting and explanting the implant device are also described.

  • Patent number: 8177853
    Abstract: A device for inducing weight loss in a patient includes a tubular prosthesis self-expandable from a collapsed position in which the prosthesis has a first diameter to an expanded position in which the prosthesis has a second, larger, diameter. In a method for inducing weight loss, the prosthesis is placed in the collapsed position and inserted into a stomach of a patient. The prosthesis is allowed to self-expand from the collapsed position to the expanded position and into contact with the walls of the stomach, where it induces feelings of satiety and/or inhibits modulation of satiety-controlling factors such as Ghrelin.

  • Publication number: 20120004590
    Abstract: A method for controlling appetite by means of a satiation device is disclosed. The device, which includes a flexible webbing defining proximal and distal openings and a biasing structure, is attached to the patient's stomach with the proximal opening positioned adjacent and below the patient's gastro-esophageal junction. The biasing structure imparts pressure against the wall of the patient's stomach adjacent the gastro-esophageal junction.

  • Publication number: 20110270410
    Abstract: A device for inducing weight loss in a patient includes a tubular prosthesis positionable at the gastro-esophageal junction region, preferably below the z-line. In a method for inducing weight loss, the prosthesis is placed such that an opening at its proximal end receives masticated food from the esophagus, and such that the masticated food passes through the pouch and into the stomach via an opening in its distal end.

  • Publication number: 20110166482
    Abstract: Methods and systems are disclosed for stimulating contents of the carotid sheath using an intravascular pulse generator and lead. The lead carries an energy delivery device such as an electrode, which is anchor within the portion of the internal jugular vein that is disposed within the carotid sheath. The energy delivery device is energized to transvenously direct energy to target contents of the carotid sheath external to the internal jugular vein. Such target contents may include nervous system elements associated with the carotid sinus baroreceptors, the carotid sinus nerve and associated nerve branches, and or the vagus nerve and associated nerve branches. The system may be used to control blood pressure and/or to lower heart rate and may be suitable for treatment of hypertension, heart failure, or other conditions.

  • Publication number: 20110153030
    Abstract: Described herein is a positioning tool having an elongate portion for carrying a medical implant. Also described is a method of positioning a medical implant using an elongate positioning tool. One form of the method includes positioning a medical implant on a distal portion of an elongate positioning tool, inserting the positioning tool with the implant thereon into a body cavity manipulating the positioning tool to position the implant into contact with tissue at an attachment location, attaching the implant to surrounding tissue at the attachment location, separating the implant from the positioning tool, and withdrawing the positioning tool from the body. In a preferred embodiment, the position of the implant is visually confirmed using an endoscope before the implant is attached to surrounding tissue. In one embodiment, the implant is a satiation device and the body cavity is the esophagus and/or stomach.

  • Publication number: 20110118545
    Abstract: A system for performing multi-tool minimally invasive medical procedures through a single instrument port into a body cavity includes a rigid tube carried by a mount. Cannulas having instrument channels and steerable distal ends extend distally from the rigid tube. During a procedure using the system, the mount is supported by an operating room fixture, and instruments are advanced through the steerable instrument channels. Manipulation of the instrument handles engages actuators positioned on the mount, which steer the distal ends of the cannulas through the action of pull cables. The distal ends of the instruments may thus be steered within the body by the distal ends of the steerable cannulas.

  • Patent number: 7931666
    Abstract: A system for enabling the insertion and removal of an embolic protection device, for capturing and retaining embolic debris which may be created during the performance of a therapeutic interventional procedure in a stenosed or occluded region of a blood vessel. The system, in an embodiment thereof, enables the device to be compressed for insertion thereof through a patient's vasculature so as to cross the stenosis in a low profile, and to enable release of compression thereof for expansion and deployment of the device at a location distal to the interventional procedure site.

  • Publication number: 20110066173
    Abstract: A system for performing minimally invasive medical procedures includes an elongate support advanceable into a body cavity. The elongate support supports a frame that carries a pair of tool cannulas, each of which has a lumen for receiving a tool useable to perform a procedure in the body cavity. The frame is expandable to orient the tool cannulas such that they allow the tools to be used in concert to carry out a procedure at a common location in the body cavity.
